Light brightness changeable electroluminescent device

Abstract

An electroluminescent device includes one or more electroluminescent laminates attached onto a bottom surface of a base panel and one or more patterns attached onto an upper surface of the base panel. The patterns each may include two or more spaces having different material of different brightnesses to generate light of different brightness through the different materials when the electroluminescent laminate is energized. The patterns may include one or more outer peripheral spaces formed around the other inner peripheral surfaces, to generate light of different brightnesses.

Description

BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention relates to an electroluminescent device, and more particularly to an electroluminescent device having light changeable structure or having lights that may be changed to different brightnesses.2. Description of the Prior ArtVarious kinds of typical light devices have been developed for attaching onto various objects, such as shoes, cycles, etc., in order to generate warning or decorative lights or patterns. The typical light devices comprise a number of light bulbs or the like for generating lights. However, the light bulbs occupy a great-size or volume that may greatly increase the volume of the light devices and that is adverse for both transportation and storing purposes.The other typical electroluminescent devices have also been developed for attaching onto various objects, and comprise electroluminescent light panel segments or materials that may be arranged in planar structure and that may occupy a relati...

AI Technical Summary

Benefits of technology

The other objective of the present invention is to provide an electroluminescent device including one or more batteries that may be easily changed by the users themselves, for allowing the working life of the electroluminescent device to be greatly increased.

Problems solved by technology

However, the light bulbs occupy a great-size or volume that may greatly increase the volume of the light devices and that is adverse for both transportation and storing purposes.

However, the electroluminescent light materials are directly energized to generate lights, such that the patterns are fixed or predetermined and may not be changed to different brightness.

However, the luminescent laminates each may also emit a specific color while energized, such that the patterns or the luminescent laminates are also fixed or predetermined and may not be changed to different brightness.

Some of the batteries may even be damaged or wetted before the typical electroluminescent devices have been sold to the users.
